“…albopictus identified in Rabat in 2016 [ 17 ] is competent for not only Zika virus transmission but also for many Arboviruses: Dengue, Chikungunya, and Yellow fever viruses [ 4 ]. Moreover, multiple cases of some imported arboviruses have been described recently in Morocco, especially Dengue [ 11 ] and Chikungunya [ 12 ]. With a suitable environment, viremic travelers caring viruses, and the potential wild distribution of known competent vectors, all key elements for potential outbreaks are present.…”

Mosquitoes transmit several agents of diseases and the presence of different species represents a threat to animal and public health. Aedes and Culex mosquitoes are of particular concern giving their potential vector competence for Arbovirus transmission. In Morocco, the lack of detailed information related to their spatial distribution raises major concerns and hampers effective vector surveillance and control. Using maximum entropy (Maxent) modeling, we generated prediction models for the potential distribution of Arboviruses vectors (Aedes aegypti, Ae. vexans, Ae. caspius, Ae. detritus, and Culex pipiens) in Morocco, under current climatic conditions. Also, we investigated the habitat suitability for the potential occurrence and establishment of Ae. albopictus and Ae. vittatus recorded only once in the country. Prediction models for these last two species were generated considering occurrence datasets from close countries of the Mediterranean Basin, where Ae. albopictus is well established, and from a worldwide database for the case of Ae. vittatus (model transferability). With the exception of Ae. vittatus, the results identify potential habitat suitability in Morocco for all mosquitos considered. Existing areas with maximum risk of establishment and high potential distribution were mainly located in the northwestern and central parts of Morocco. Our results essentially underline the assumption that Ae. albopictus, if not quickly controlled, might find suitable habitats and has the potential to become established, especially in the northwest of the country. These findings may help to better understand the potential distribution of each species and enhance surveillance efforts in areas identified as high risk.

“…4,9,10 Cases of imported chikungunya from Bangladesh have also been reported in literature. 11 The clinical manifestation of chikungunya fever is like that of other arboviral infections (like dengue) including fever, arthritis/arthralgia and rashes. In countries with endemic dengue infections like Bangladesh, it is important to differentiate clinically between the two; as NSAIDs for pain relief in arthritis of chikungunya may worsen haemorrhagic manifestations of dengue.…”

Background: Chikungunya is a rapidly spreading viral infection of global concern. Initial presentation of chikungunya infection is often indistinguishable from other viral infections. In Bangladesh, chikungunya is an emerging infection. In this report, we describe socio-demographic, clinical and laboratory characteristics of chikungunya in a selected group of Bangladeshi patients. Methods: A multi-center descriptive study was done including adult patients with chikungunya virus infection from July 1, 2017 to October 31, 2017. Diagnosis of chikungunya virus infection was confirmed by reverse transcriptase polymerase chain reaction (RT-PCR) or immunoglobulin M (IgM) against chikungunya. Results: Total patients were 107 including 61 (57%) males. Mean age of the study participants was 35.6 (range 19-84) years. Ninety three (86.9%) patients presented with fever and 14 (13.1%) patients (with history of recent fever) presented due to joint pain. Most (93, 86.9%) patients were managed as out-patient basis; while 14 (13.1%) patients required hospitalization. Common features were fever/history of fever, joint pain, rash and lymphadenopathy. Out of 93 patients who presented with fever, 79 (85%) had concomitant arthralgia/ arthritis, 70 (75.3%) had persistent joint symptoms beyond febrile illness requiring paracetamol, 63 (67.2%) patients had joint pain beyond 3 weeks (sub-acute phase) requiring paracetamol, non-steroidal antiinflammatory drugs or corticosteroids and 11 patients had passed 3 months since symptom onset (chronic phase) and only one (9%) had joint symptoms requiring hydroxychloroquine. There was no death. Conclusion: Clinical manifestation of chikungunya virus infection was comparable with other viral infections but arthritis/arthralgia was an important differentiating point. As chikungunya is an emerging infection in Bangladesh, physicians should have a high index of suspicion and care should be taken to exclude other viral infections specially dengue.
